yep i'll give you something to laugh about today the sources i have extensive experience with:
DAC-AH stock, DAC-AH modded, Stock Zhaolu D2.0A, the OMZ of course, 0404 USB, 0404 PCI, Chaintech AV-710 and some other crappy PC sound cards not worth mentioning.
As you can see my experience doesn't hold a candle to what other guys here have heard, but the OMZ is such a huge step up from anything I have ever heard that I am completely satisfied with it considering its cost (lots of other stuff are out of my budget)
p.s. my previous comments about some finding its sound quality acceptable include your own posters here 5678 and Jon L, but also some other posters on head-fi who have heard really good gear and vouch for it.
